My soft version: ImageMagick 6.7.9-0 PNG * PNG rw- Portable Network Graphics (libpng 1.2.52) For more information on the PNG format, see http://www.libpng.org/ . PNG24 * PNG rw-opaque 24-bit RGB (zlib 1.2.8,1.2.1.2)
I tried ImageMagick-6.9.1-6 and libpng-1.6.17 zlib-1.2.8, all this is the latest version, but there is still an error
try this png image and help me ...
